1. Field of the Invention

The invention is based on a priority patent application EP 10171710.6which is hereby incorporated by reference.

2. Description of the Related Art

The invention relates to an exterior rear view mirror of an exteriorrear view mirror assembly for a motor vehicle with an exterior rear viewmirror housing, a base bracket at least partly accommodated in theexterior rear view mirror housing, a frame with walls, which surround anopening arranged on the rear side of the exterior rear view mirrorhousing, for a mirror glass, and an adjusting device, attached to thebase bracket, for the mirror glass, wherein the frame being attached tothe base bracket by means of the adjusting device; and

a process for assembly of an exterior rear view mirror of this type withan exterior rear view mirror housing, a base bracket, at least partlyaccommodated in the exterior rear view mirror housing, a frame withwalls, which surround an opening arranged on the rear side of theexterior rear view mirror housing, for a mirror glass, and an adjustingdevice, fixed on the base bracket, for the mirror glass, wherein thefollowing process steps: alignment of the frame and the adjusting devicein relation to one another and attachment of the frame to the basebracket by means of the adjusting device.

An exterior rear view mirror assembly for a motor vehicle consists, forexample, of a mirror base arranged on the motor vehicle, which can becovered by means of a mirror base cover, and an exterior rear viewmirror arranged on the mirror base. The exterior rear view mirrorincludes an exterior rear view mirror housing, which, inter alia, housesthe base bracket assigned to the mirror base.

The mirror base and the base bracket are hinged together, so that theexterior rear view mirror can be pivoted about a hinge axis in relationto the mirror base from an operating position into a folding positionand vice versa. The mirror base and base bracket can be produced fromdie-casting material, for example, from the same material.

An adjusting device for a mirror glass, driven by an electric motor, forexample, is arranged on the base bracket. The adjusting device acts on abacking plate, on which the mirror glass is arranged. The mirror glasscan be mounted onto the backing plate by means of an adhesiveconnection. The backing plate can be guided to and/or mounted on theadjustment device and/or the base plate. The term ‘backing plate’ hererefers to any type of bracket, which comprises at least one bracketsurface, with a plane or vaulted design, closed or in a non-continuousgrid, for example, honeycombed, on which it is suitable to attach amirror glass, for example by means of an adhesive connection or byclipping e.g. locking means, protruding behind the perimeter of thebracket surface and arcing inwards towards the centre of the bracketsurface, seen from the perimeter.

On its rear side, facing away from the direction of movement of thevehicle in the operating position, the exterior rear view mirror housingcomprises an opening, through which the mirror glass is visible, or inwhich the mirror glass is arranged. In order to ensure that the mirrorglass is adjustable, a distance is kept on all sides between the mirrorglass or backing plate and the walls of the exterior rear view mirrorhousing surrounding the opening, so that a gap is given around themirror glass between the walls of the exterior rear view mirror housingsurrounding the opening.

In production of motor vehicle parts, such as an exterior rear viewmirror assembly or an exterior rear view mirror, there are many legalregulations to take into account. A legal regulation to protect thirdparties from injuries, for example, provides permissible minimum radii,which must at least be kept, at least on unprotected, exposed points.These required minimum radii cannot be kept, for example, in mirrorglasses. In order to meet the legal requirement, though, it is known toprotect the mirror glass by a circumferential frame. The frame surroundsthe opening provided for the mirror glass on the rear side of theexterior rear view mirror housing, so that the edges of the mirror glassare not exposed. Here the frame can only surround the walls surroundingthe opening, or form a housing section lying around the opening for themirror glass with the walls surrounding the opening. The externalcontour of the frame, forming a part of the external side of theexterior rear view mirror housing in the process, here maintains thelegally predefined minimum radii around the mirror glass, without themirror glass being exposed itself with immediate accessibility to itsedges.

In addition to, or instead of, an electromotive activation for theadjustment device of the mirror glass, the exterior rear view mirror canaccommodate one or several additional electrical components. Examples ofelectrical components of this type are:

-   -   a turn signal indicator,    -   an entry light,    -   a heatable mirror glass,    -   an electro-chromatically dimmable mirror glass,    -   a detection module and/or warning display module for a driving        assistance device, such as blind spot monitoring, a lane        departure warning, approach monitoring, or similar,    -   a sensor for detecting driving and/or surrounding conditions,        such as for example, temperature, brightness, degree of        pollution, lighting situation, for example, in order to        automatically heat the mirror glass, or to dim        electro-chromatically, for example.

In addition, the exterior rear view mirror can comprise one or severalcombinations of the electrical components given as examples.

The electrical components in the exterior rear view mirror are connectedto a power supply on the vehicle side, and/or to a control device on thevehicle side, for example, by means of an electrical connection throughthe mirror base, for example by a vehicle electrical system and/or a bussystem. The electrical connection consists, for example, of a cableharness with several cables, if necessary, each with separate plugconnections to the electrical terminal of the electrical components, ineach case individually or in groups, and at least one electrical plugconnection for continuative electrical contacting on the vehicle side.

For example, in order to simplify the assembly of the differentcomponents, at least partly housed in the inside of the exterior rearview mirror housing, component groups, as well as, if necessary, theirelectrical connections between each other and/or with a control unithoused on the motor vehicle side, the exterior rear view mirror housingcan be designed in at least two parts. A first housing part forms thehousing base, for example, and a second housing part forms the housingcover. At the same time, one of both housing parts can include the framewith the walls surrounding the opening, as well as, if necessary, thehousing section lying around the opening for the mirror glass.

In summary, an exterior rear view mirror of an exterior rear view mirrorassembly consists of several components connected to each other, forexample, a one-piece or multi-piece exterior rear view mirror housing,which consists of a housing base, housing cover and the frame, ifnecessary, a base bracket housed therein, an adjustment device arrangedthereon, a mirror glass and a backing plate bearing this and attached tothe adjustment assembly, as well as, if necessary, at least oneelectrical component, at least partly housed inside the exterior rearview mirror housing, for example, an electromotive activation for theadjustment device.

SUMMARY OF THE INVENTION

The object is in the development and production of motor vehicle parts,such as perhaps an exterior rear view mirror assembly or an exteriorrear view mirror, a simple, time-saving, and cost-effective productionand assembly.

Exterior rear view mirror assemblies or exterior rear view mirrors withassembly concepts, which include a multiplicity of time-consuming worksteps for the production of mechanical and/or electrical connectionsbetween individual components and/or component groups in each case, arecontrary to this aim.

An exterior rear view mirror of a motor vehicle is known in U.S. Pat.No. 7,448,589 B2. The exterior rear view mirror consists of a basebracket, a one-piece exterior rear view mirror housing arranged on thebase bracket, with a rear-facing opening for a mirror glass, and a frameintegrated into the exterior rear view mirror housing with the wallssurrounding the opening, as well as an electromotively activatedadjusting device, arranged on the base bracket, for a backing plate, onwhich the mirror glass is arranged. For the assembly of the exteriorrear view mirror, firstly, it is necessary to connect the base bracketand the exterior rear view mirror housing together, and following this,to attach the electromotively activated adjusting device to the basebracket through the rear-facing opening, which is surrounded by theframe on the exterior rear view mirror housing.

The disadvantage of this is the complex, time-intensive andcost-intensive assembly of the components and the electrical components,caused by poor accessibility, as well as their connections to oneanother through the rear-facing opening surrounded by the frame.

An object of the invention is the creation of an improved exterior rearview mirror for a motor vehicle, which allows for a simple andcost-effective production and assembly.

The object is achieved by

an exterior rear view mirror with an exterior rear view mirror housing,a base bracket, at least partly accommodated in the exterior rear viewmirror housing, a frame with walls, which surround an opening arrangedon the rear side of the exterior rear view mirror housing, for a mirrorglass, and an adjusting device, attached to the base bracket, for themirror glass, wherein the frame being attached to the base bracket bymeans of the adjusting device; and

process for assembly of an exterior rear view mirror with: an exteriorrear view mirror housing, a base bracket, at least partly accommodatedin the exterior rear view mirror housing, a frame with walls, whichsurround an opening arranged on the rear side of the exterior rear viewmirror housing, for a mirror glass, and an adjusting device, fixed onthe base bracket, for the mirror glass, wherein the following processsteps: alignment of the frame and the adjusting device in relation toone another and attachment of the frame to the base bracket by means ofthe adjusting device.

A first subject of the invention thus concerns an exterior rear viewmirror with:

-   -   an exterior rear view mirror housing,    -   a base bracket, at least partly accommodated in the exterior        rear view mirror housing,    -   a frame with walls, which surround an opening, arranged on the        rear side of the exterior rear view mirror, for a mirror glass,        and    -   an adjusting device, fixed on the base bracket, for a backing        plate, on which the mirror glass is arranged.

The exterior rear view mirror is characterized in that the frameprovided for surrounding the mirror glass is fixed on the base bracketby means of the adjusting device.

Advantages resulting from this, in relation to the prior art, areunrestricted accessibility to the electrical and mechanical connectionsto be produced in the exterior rear view mirror housing, through tofastening the adjusting device on the base bracket. Inter alia, furtheradvantages are given in that the frame, still before fastening of theadjusting device on the base bracket, can be aligned so that it iseasily accessible in relation to the adjusting device, and if necessary,can be fixed on and/or attached to this.

The frame can comprise a part provided for its attachment to the basebracket by means of the adjusting device.

The section can be formed in the shape of a bowl, whereby the bowl edgeforms the walls surrounding the opening provided on the rear side of theexterior rear view mirror housing. In the region of the bowl base, theframe is attached to the base bracket by means of the adjusting device.

The bowl-shaped section can have a lattice form at least between thebowl edge and the bowl base. This serves for both a saving of weight, aswell as a visual control and/or assembly aid during assembly of theexterior rear view mirror, for example, in order to see whether themechanical and electrical connections, provided if necessary, areproduced properly, and that the electrical connections, provided ifnecessary, run properly and do not become jammed or disconnected.

The fastening of the frame to the base bracket by means of the adjustingdevice can take place by means of fastening means at least also providedfor the attachment of the adjusting device to the base bracket.

Alternatively or additionally, the attachment of the frame to the basebracket by means of the adjusting device can be effectuated by the framebeing held tightly to the base bracket itself, for example, by theadjusting device, and/or by being clamped in a friction-locked manner,for example, as a section of the frame, which is provided for attachmentto the base bracket by means of the adjusting device, is arrangedbetween the adjusting device and the base bracket.

Here, the section of the frame provided for attachment to the basebracket by means of the adjusting device can at least partly encompassand/or engage behind the adjusting device, seen from the openingprovided on the rear side of the exterior rear view mirror housing forthe mirror glass.

In a part of the section at least partly encompassing and/or engagingbehind the adjusting device, through-openings can be provided at leastfor the fastening means serving for the attachment of the adjustingdevice to the base bracket, these so that the frame is attached to thebase bracket by means of the adjusting device itself, and in addition,by means of the fastening means provided for its attachment to the basebracket.

Optionally or additionally, the frame can be connected to the adjustingdevice. Preferably, this connection is situated on the side of theadjusting device facing the base bracket, particularly preferably,between the adjusting device and the base bracket.

For one of the named attachments and/or for production of one of thenamed connections, both interlocking and friction-locking connectiontypes are suitable, such as by means of screws, bolts, shear pins, nuts,nails, staples, rivets, for example, as well as firmly bonded connectiontypes, such as by means of welding, soldering, or adhesive bonding, forexample.

The frame can form a housing section surrounding the opening for themirror glass. The housing section here forms at least one part of anexternal contour of the exterior rear view mirror housing.

The frame can form or include a housing part, comprising the opening forthe mirror glass, of an exterior rear view mirror housing formed in atleast two parts, or can be formed or included by a housing part of thistype.

The exterior rear view mirror housing can here consist of at least afirst housing part and a second housing part, both of which can beconnected to the base bracket, which is provided if necessary. One ofboth housing parts can include a housing section lying around theopening for the mirror glass, as well as, if necessary, the frame withthe walls surrounding the opening. The first housing part and the secondhousing part border each other along at least one connection joint. Atleast the housing part including the frame with walls surrounding theopening, as well as, if necessary, the housing section lying around theopening for the mirror glass, is attached to the base bracket by meansof a bolted connection, for example, by means of the adjusting device.

It is important to emphasise that alternatively or additionally to abolted connection, any other force-fit and/or interlocking and/or firmlybonded connection methods, such as, for example, glued or welded lockingconnections, riveted joints or combined plug and screw or lockingconnections can be used here if necessary. As an example of this, alocking connection, alone or suitable in combination with anotherconnecting method, also denoted as a clip connection or a snapconnection, includes corresponding locking elements, of which at leastone is elastically deformable, and following a deformation, hooksdetachably or inextricably with at least another to produce the lockingconnection. Examples of corresponding locking elements of this type area rearward engagement and an elastically deformable locking meansengaging therein.

A second item of the invention relates to a process for assembly of anexterior rear view mirror for a motor vehicle. The exterior rear viewmirror includes:

-   -   an exterior rear view mirror housing,    -   a base bracket, at least partly accommodated in the exterior        rear view mirror housing,    -   a frame with walls, which surround an opening, arranged on the        rear side of the exterior rear view mirror, for a mirror glass,        and    -   an adjusting device, fixed on the base bracket, for a backing        plate, on which the mirror glass is arranged.

The process is characterized in that the frame, provided for borderingthe mirror glass, and the adjusting device are firstly aligned inrelation to one another, as well as connected to one another ifnecessary, and the frame is subsequently attached to the base bracket bymeans of the adjusting device.

The process permits the advantages of a previously described exteriorrear view mirror to be used during its assembly. Embodiments of theprocess result from the previously described different options for theembodiment of the exterior rear view mirror and its components,component groups, as well as electrical components provided ifnecessary.

Further features of the invention result from the claims, descriptionand drawings.

DETAILED DESCRIPTION OF THE DRAWINGS

An exterior rear view mirror 01, partly shown in FIGS. 1 and 2, of anexterior rear view mirror assembly for a motor vehicle essentiallyincludes an exterior rear view mirror housing, not shown in more detailfor the sake of clarity, a base bracket 02 at least partly housed in anexterior rear view mirror housing, a frame 03 and an adjusting device04, for a mirror glass, attached to the base bracket 02. The adjustingdevice 04 preferably has an electromotive activation. An adjustingdevice 04 of this type can thus be denoted as an actuator for the mirrorglass.

The frame 03 has walls 05, which surround an opening 06 arranged on therear side of the exterior rear view mirror housing, for a mirror glass.

The frame 03 serves for bordering the mirror glass. The frame 03 allowsfor fulfilling a legal regulation to protect third parties frominjuries, for example, which gives permissible minimum radii, which mustat least be observed, at least on unprotected, exposed points. The frame03 protects the edges on the borders of the mirror glass, so that theseare not exposed. This is necessary, since the minimum radii required bythe legal regulation cannot be met in mirror glasses.

The adjusting device acts on a backing plate, on whose side facing theopening 06 on the rear side of the exterior rear view mirror housing 01,the mirror glass is arranged.

The frame 03 is attached to the base bracket 02 by means of theadjusting device 04.

The attachment of the frame 03 to the base bracket 02 by means of theadjusting device 04 takes place by means of at least fastening means 07also provided for fastening the adjusting device 04 to the base bracket02. These fastening means 07 can be screws, for example.

The frame 03 can comprise a section 08 provided for its attachment tothe base bracket 02 by means of the adjusting device 04. Seen from theopening 06 for the mirror glass, provided on the rear side of theexterior rear view mirror housing, the section 08 surrounds and/orengages behind the adjusting device 04, at least in parts.

In a part 09 of the section 08 at least partly surrounding and/orengaging behind the adjusting device 04, through-openings 10 for thefastening means 07 serving for attaching the adjusting device 04 to thebase bracket 02 can be provided. In addition, in the part 09 of thesection 08 at least partly surrounding and/or engaging behind theadjusting device 04, at least one through-opening 11 can be provided forat least one surface of the adjusting device 04 coming into contact withthe base bracket 02.

The section 08 is preferably designed in a bowl form. The bowl edge 12forms or includes the walls 05 surrounding the opening 06 provided onthe rear side of the exterior rear view mirror housing. In the region ofthe bowl base 13, the frame 03 is attached to the base bracket 02 bymeans of the adjusting device 04.

The bowl-shaped section 08 can have a lattice form at least between thebowl edge 12 and the bowl base 13.

The frame 03, for its attachment to the base bracket 02 by means of theadjusting device 04, is held tightly by the adjusting device 04 and/oris clamped in a friction-locked manner. As an example, for a secure,interlocking mounting, recesses 14 and/or protrusions 15, for example,can be provided on the frame 03 and related protrusions and/or recessescan be provided on the adjusting device 04. For example, severalrecesses 14 and protrusions 15 can be provided on the bowl base 13, e.g.equally distributed over the extent, lying around the through-opening11. On its surface in contact with the base bracket 02 through thethrough-opening 11, the adjusting device has surface portionscorresponding to the recesses 14 and protrusions 15.

Entrances 16 for the fastening means 07 are provided on the base bracket02. The entrances can be designed, for example, as openings or holese.g. in the form of blind holes, into which are screwed fastening meansimplemented as tapping screws, for example. Alternatively, the openingsof the entrances 16 can be provided with an internal thread, into whichfastening means designed as threaded screws can be screwed. In theprocess, the entrances 16 can have the external shape of domes standingon the base bracket, which are equipped, in each case, with a holerunning along its axis, provided with an internal thread, if necessary.

It is important to emphasise that the entrances 16 and the fasteningmeans 07 can also be designed the other way round to the way previouslydescribed. In the present execution example, this means that theentrances 16 can be provided with threaded rods, for example, whichproject through the through-passage openings 10 in the bowl base 13 ofthe section 08 of the frame 03 and through the adjusting device 04, andthe fastening means 07 are designed as nuts, for example.

It is also important to emphasise that the frame 03, independently ofthe attachment to the base bracket 02 by means of the adjusting device04, can be separately connected to the adjusting device 04. For thispurpose, for example, one or several connections e.g. one or severallocking and/or bolted connections between the frame 03 and the adjustingdevice 04 can be provided. The frame 03 is connected here to theadjusting device 04, preferably to the side of the adjusting device 04facing the base bracket 02, e.g. between the adjusting device and basebracket.

The frame 03 can form a housing section surrounding the opening 06 forthe mirror glass. The housing section here forms at least one part 17 ofan external contour of the exterior rear view mirror housing.

In order to increase the stability of the exterior rear view mirror 01following the attachment to the base bracket 02 by means of theadjusting device 04, the frame 03 can also be connected to the basebracket 02 by means of fastening means provided for this purpose.

A process shown schematically in its course in FIG. 3 for assembly of anexterior rear view mirror 01 with:

-   -   an exterior rear view mirror housing,    -   a base bracket 02, at least partly accommodated in the exterior        rear view mirror housing,    -   a frame 03 with walls 05, which surround an opening 06 arranged        on the rear side of the exterior rear view mirror housing, for a        mirror glass, and    -   an adjusting device 04, attached on the base bracket 02, for a        backing plate, on which the mirror glass is arranged,        essentially consists of two process steps I, II, at least in a        basic form.

The process starts in a first process step I with the frame 03 and theadjusting device 04 being aligned in relation to one another. During thealignment in relation to one another, both the frame 03 and theadjusting device 04 are preferably not connected to any other componentor any other component group of the exterior rear view mirror, so thatboth the frame 03 as well as the adjusting device 04 can be handledfreely.

In a second process step II, the process provides an attachment of theframe 03 to the base bracket 02 by means of the adjusting device 04. Forthis purpose, the frame 03 previously aligned to the adjusting device isthus attached to the base bracket 02, as the adjusting device 04 isattached to the base bracket. This therefore saves a separate work stepof a separate attachment of the frame 03 to the base bracket 02. Aseparate work step of this type for attachment of the adjusting deviceto the base bracket, required according to the prior art, after theframe has already been mounted on the base bracket, is also complicatedto achieve, since accessibility through the frame is very limited.

In an alternative arrangement of the process, indicated by the dottedarrows A and B, a third process step III takes place after the firstprocess step I and before the second process step II. This third processstep III provides that the frame 03 is attached to the adjusting device04 before the attachment to the base bracket by means of the adjustingdevice 04. In the process, the adjusting device 04 and frame 03 arefreely accessible on all sides, so that an additional process step ofthis type can be carried out easily, and in all cases, there is a savingin relation to an attachment of the adjusting device 04 to the basebracket, according to the prior art, which could only be implementedwith high expenditure of time, after the frame has already been attachedto the base bracket.

Inter alia, advantages of the invention are given in that currently inthe prior art, in a first work step, the frame must first be attached tothe base bracket by means of separate screws, before e.g. electricaland/or mechanical connections must then be produced in further steps inthe inside of the exterior rear view mirror, which has pooraccessibility limited by the frame. In a separate work step, in theprior art, the adjusting device must then also be attached to the basebracket by means of separate fastening means, e.g. also screws.

The present invention facilitates either the saving of or the simplifiedexecution of a work step, since the frame 03 is now attached to the basebracket 02 by means of the adjusting device 04.

The invention is particularly commercially applicable in the productionof exterior rear view mirror assemblies for motor vehicles.
